The Portland man who stripped naked going through security at PDX now faces a $1000 federal fine. John Brennan was cleared of local charges for indecent exposure, and says that the federal government is now trying to fine him for interference and intimidation of TSA screeners. The screeners wanted to conduct a hand inspection after detecting nitrates on his clothing; that’s when he stripped to prove he wasn't carrying explosives. He expects the fine to be upheld and he plans to appeal the fine in hopes of eventually bringing change to the way screenings are conducted.
